Answer:
$300,000
Step-by-step explanation:
Calculation for the annual estimated taxable income as of the end of the third quarter
Using this formula
Annual estimated taxable income=2 × (First quarter taxable income + Second quarter taxable income)
Let plug in the formula
Annual estimated taxable income=2 x ($100,000 + $50,000 )
Annual estimated taxable income=2×$150,000
Annual estimated taxable income=$300,000
Therefore the annual estimated taxable income as of the end of the third quarter will be $300,000
